A free online calculator for US freelancers and 1099 contractors. Type in what a client just paid you and see what to move into your tax account today, and what’s actually yours to spend.

What it shows
• Self-employment tax (Social Security and Medicare)
• Federal income tax at your bracket
• State income tax at your state’s rate
• One set-aside amount, rounded up, plus what’s left to spend
• A countdown to the next estimated tax payment date

Who it’s for
Sole proprietors and single-member LLCs filing Schedule C.

What it isn’t
A quick estimate, not tax advice. It leans high on purpose, so you save a little more rather than come up short. Check your situation with a tax professional.

Free, works on your phone, nothing to download.
